Specification of Letters Patent.

Patented June 11, 1907.

Application filed November 28,1906. Serial No. 345.444.

' In all whom, it may concern.-

Be it known that I, ALFRED W. Rnrsnn, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Heat-Conductor for Drop-Light Fixtures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures and letters of reference marked thereon, which form a part of this specification.

Myinvention relates to lighting appliances, and is intended more particularly for use inconnection with dining-room drop-light fixtures of the class employing Welsbach or other gas burners as the lighting medium.

The object of my invention is the provision in combination with fixtures of this nature of simple and efficient means for conducting from the fixture parts the heat generated by the associated burner, whereby the deleterious effect of the heat on such parts is obviated and the life and beauty of the fixture consequently prolonged.

Further objects of the invention as Well as the operation, construction and arrangement of the parts thereof will be apparent by reference to the following specification, and to the accompanying drawings, in which,-

Figure 1 is a side elevation of a dining room fixture embodying the features of my invention, with the dome or shade thereof and the features comprising the invention partially in section. Fig. 2 is a side elevation of the heat conductor. Fig. 3 is a similar view of the fixture with the hood of the heat conductor in central transverse section. Fig. 4 is a top plan view of the conductor hood with the associated pipes removed, and

- Figs. 5 and 6 are different constructions of the member which braces the upper ends of the conductor pipes.

Referring to the drawings, 1 designates a dining-room drop-light fixture of any suitable construction or design, 2 the dome or shade thereof, and 3 the portion inclosing the burner.

As the heat rising from the burner of the fixture is quite intense, it is important that provision be made for carrying off the highly heated products of combustion to prevent them acting on the solder, lacquer, and other fusible parts of the fixture and otherwise injuring the same. This I accomplish by surmounting the burner part with a hood 4, preferably of circular construction and formed with the depending outwardly flared wall 5, which overhangs said part as shown. The top of this hood is provided with a central opening 6 for receiving the neck or contracted part 7 of the burner and is supported by resting on the subjacent flared or enlarged part 8 of the burner, as shown, or in any other convenient manner. The hood top is also provided adjacent its edge with one or more openings 9, preferably but not necessarily of elongated shape, to the edges of which the flared mouth-pieces 10 leading to the superimposed conductor tubes 11 are secured. These tubes extend upwardly from the hood and their upper ends pass between the dome and fixture and terminate just below the upper edge of the dome so that they are practically hidden from view. To prevent the too highly heating of the tubes 11 by the gases passing therethrough each is incased in a larger concentric tube 12, which is of sulficient diameter to provide a small annular chamber around the tube 11 for the passage of cool air therethrough, said chamber being open at its bottom and top for that purpose, as shown. Rods or pins 13 pass transversely through the sets of tubes 1112 to support the latter, and the tubes are retained in concentric relation by the interposed washers or spacing members 14 carried by said rods or pins. The sets of tubes 11-12 are prevented from lateral movement relative to the supply tube 16 of the fixture by a bracing member 17, which is provided with a central opening for receiving said supply-tube and has its ends formed with openings 18 for receiving the tubes 12. As the varying sizes of different fixtures cause the upper ends of the sets of tubes 1112 to be spread a greater or less distance apart it is found convenient to make the bracing member 17 longitudinally adjustable. A construction of this character is shown in Fig. 6, in which a designates the body of the member, which has the fixture embracing opening I), and c the tube embracing parts, each of which has an arm d slidingly cooperating with an arm on the body portion. The arms (1 are formed with ears e, which are bent to slidingly embrace the arms of the body as shown, and the outward movement of the parts 0 relative to the body is limited due to the ears 0 coacting with ears f on the arms of the body. Regis- 'tering depressions g in the cooperating arms When burners of the inverted Welsbach type, such as shown in the drawing are employed, the heat rising therefrom acts upon and is conducted throughout the superimposed metal parts of the fixtures to the material injury thereof. This is prevented by interposing an insulating nipple in the fixture at any convenient point adjacent its lower end, as between the parts 7 and supply tube 16 thereof. This nipple comprises the two disk-like members 19 19, each having its outer face formed with a threaded teat, said members being spaced by asbestos 20, and the whole bound together bysecuring pins 21.

While I have shown my invention in association with a burner of the inverted Welsbach type, I do not wish to be understood as restricting myself to such use as it can be used in connection with any other type of gas or other burners in which a considerable amount of heat is generated when burning.

Having thus described my invention, what I claim asnew and desire to secure by Letters Patent, is,-

1. The combination with a dining-room drop-light fixture, and the burner having a contracted neck, of a hood provided with a central opening which closely embraces the contracted neck of the burner, and with oblong openings at the sides of said central I ,see

ture, and the burner, of a hood surmounting the burner and having openings therein, heat conductor tubes leading upwardly from the openings, and means adjustable relative to the fixture for bracing the tubes.

3. The combination with a droplight fix- 2. The combination with a drop-light fix ture, and the burner, of a hood surmounting the burner and having a central opening embracing the fixture, whereby it is supported, and openings in its top, flared mouth-pieces communicating with said latter openings and terminating in upwardly extending tubes, and means adjustable relative to the fixture for bracing the tubes.

4. The combination with a drop light fixture, of a hood surmounting the burner and having openings therein, heat conductor tubes leading upwardly from the openings, and means for bracing the tubes relative to the fixture, said means being adapted to permit a lateral adjustment of the tubes.

In testimony whereof 'I have hereunto signed my name to this specification in the presence of two subscribing witnesses.

ALFRED WV. REISER.
